Stresses above those listed under ”Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and

functional operation of the device at theseor any other conditions abovethose indicated in the operational sections of this specification is not implied.

Exposure to absolute maximum rating conditions for external periods may affect device reliability.

fan-out and transition-time requirements. A third

cascading option makes use of the Q’ output from

the 1/2 stage, which is available on the next nega-

tive-going transition of the clock after the Q output

occurs. This delayed output, like the delayed clock
